Cosmetics, food and apparel all registered double-digit growth last month, whereas sales of the hard-hit auto sector also rose 8.9 percent compared with same time in the previous year.

Global product debuts, revitalizing time-honored Chinese brands and imported product festivals, were highlights among the 84 key events and 470 characteristic activities under the ongoing initiative, whereas livestreaming has been a major thrust promoting omnichannel sales.

For the second phase of the promotion, which runs through the end of June, the metropolis outlined a batch of major events, such as nightlife fairs, trendy-show festivals and the June 18 mid-year promotion normally carried out by e-commerce platforms, as well as a number of district-steered activities.
